A little cheap, but is what is asked

I have three Sony cameras, which use three different types of batteries and require three different packs:
NP-FM50 (for my old bridge), NP-FV50 for my HD camcorder, and NP-FW50 for my Nex6 hybrid.
The last two are the same size and the same current rating, but the connectors are different.
You dreamed, Sony did -;)

Sony seems you made a more advanced charger that it (with display of remaining battery time), but its price is prohibitive.
So I pulled over it, which seems to do the trick.
It has the advantage of being complete with plugs EU, UK and cigarette lighter.
The battery gets easily his place, and charging is carried out fairly quickly (2 hours).
